I was working on the CVA Frontier rifle I picked up a while back. Had it apart to refinish the stock and decided to compare the lock with a Traditions Kentucky pistol that is in my collection. Sun of a gun, the cap locks are interchangeable which was a bit of surprise. Next thing I know I'm pulling a flintlock off a second Traditions pistol just because I had to scratch an itch and was a little bored on a rainy day and found that the Traditions pistol flintlock is pretty much a bolt-on replacement also. Humm that means I could turn the CVA Frontier caplock rifle into a flinter by just swapping the locks and replacing the nipple bolster with a vent liner as long as everything lines up. For what I paid for the rifle it's almost worth giving it a try.
Don't think I'm going to do it but it does sound like a fun and easy conversion. I would have to part out my flinter pistol to do it or convert the pistol into a caplock which I already have. Just some thoughts on a rainy day.
